New drug for one in five breast cancers

Biological therapies can help fight breast cancers caused by rare, inherited genetic errors like the BRCA one actress Angelina Jolie carries.

Now a new study by experts at the Wellcome Trust Sanger Institute suggests these targeted drugs may also work in many other women who do not have these risky genes.

The drugs could be effective in one in five breast cancers, say the researchers.

That's 20% of patients - far more than the 1 to 5% who develop the cancer alongside having faulty BRCA genes.
